edit: title should read implore - my typing error!
Basically, unless you have a really good excuse (or you live more than, say, 50 miles from the park) you should ride to and round it today.
It is beautiful. There's no wind, there is a thick dusting of frost everywhere, it's fairly quiet in terms of traffic and there are no icy patches as far as I could see. I just spent the last few hours in there training and, granted, it's a bit nippy (-2 degs according to my Vetta) but well worth the pain. In all honesty, I'm typing this while my feet and hands warm up sufficiently that I may have a shower without them burning, but I would go out again if I could (albeit with a camera).
That is all. Apologies to those who do not live close enough to experience this today
